Neurons are the longest cells. They range in size, some can be 3 feet long. Hope this helps
Answer:
The protein is too large to simply diffuse across the phospholipid bilayer of the cell, so it uses phagocytosis to diffuse across, where it is contained in a vesicle and pinched into the cell? Credits to yahoo answer. Hope I could help sweets.
Cell membranes acts as a barrier for the large,charged and polar molecules due to their hydrophobic nature.
These molecules are transported with the help of membrane proteins such as carrier proteins across the plasma membrane by a process known as facilitated diffusion. These membrane proteins diffuse larger molecules across the cell membrane that cannot be transported by simple diffusion.
Hydrophobic effect is the tendency of non polar molecules (hydrophobic) in a solvent that is polar to interact with each other resulting to a hydrophobic interaction. These non polar molecules are called hydrophobes and are made of long chains of carbon that are water hating (do not interact with water). In this case,the hydrophobic interactions are most likely to occur on the core of a water soluble protein.
Chemically speaking, enzymes are composed of chains of amino acids, and they are considered to be a type of protein.
